I just upgraded to iOS 10 on my iPhone 5. Besides slowing down my phone greatly, the messages app has gotten cluttered with useless features. One of these is that each contact's photo now shows up at the top of the screen when I am messaging them. Besides the fact that: 1. most of my contacts don't have photos (so I just see giant initials), and that 2. the photos are too small to distinguish anything for the contacts I have that DO have photos, I have a problem with how much space these photos take up on the screen. There's just not enough screen real estate to justify showing me 2 less lines of messages in order to show me giant bubble initials or a microscopic static image of someone.
So, how do I remove contact photos from messages in iOS 10?
